RESUMEN
The effect of kanamycin on the kidney function and the possibility of decreasing its side effect of pyrimidines were studied in240 children at the age of 2 month to 14 years (161 children with acute and chronic osteomyelitis and 79 children with staphylococcal destruction of the lungs). Kanamycin used in doses of 15000 and 25000 Units/kg of the body weight for 6 to 7 days in treatment of the children with staphylococcal destruction of the lungs, acute and chronic osteomyelitis had no nephrotoxic effect. Combination of kanamycin with pentoxyl, pryimidine derivative significantly improved the kidney function, which was evident from the content of the residual nitrogen in the blood serum and increased glomerural filtration. Combined use of kanamycin with pentoxyl promoted a decrease in albuminuria and leucocyturia. The data of the study provided recommendation of increased therapeutic doses of kanamycin, up to 15000--25000 Units/kg of the body weight in accordance with the recommendations under conditions of constant control of the kidney function.
